Infoscreen for live music performing with MIDI equipment
In case you're playing synthesizers with a couple of people to a 4/4 beat, all synchronized to one MIDI clock, Blazing Baton might be useful.
- Indication of incoming MIDI clock as a 16 bar loop
- Realtime displaying of channel separated "Hot keys" based on configurable calculation
DEMO with fake midi events
- Modern webbrowser that supports Web MIDI API
- MIDI interface connected to the pc
- receive MIDI clock signal
- receive MIDI noteon/noteoff events on different channels and/or MIDI inputs
Currently you have to configure Blazing Baton directly at the very bottom of index.htm. There are plans to create a configuration GUI but for now you have to deal with a javascript configuration object.
Further It is highly possible that those names get changed until the first release.
Listening to incoming MIDI events does only occur for inputs that are activated by configuration. Doublecheck for misspelling! Otherwise incoming events will be ignored!
Define on which MIDI input Blazing Baton should listen for MIDI clock events.
NOTE: In case you define multiple inputs that are sending the clock simultaneously the tempo will be doubled.
for Example
var blazingOptions = {
inputNames: {
clock: [
"MIDIIN16 (iConnectMIDI4+)"
]
}
};Define on which MIDI input Blazing Baton should listen for MIDI noteon/noteoff events. for Example
var blazingOptions = {
inputNames: {
notes: [
"MIDIIN16 (iConnectMIDI4+)",
"MIDIIN15 (iConnectMIDI4+)"
]
}
};Here you can assign colors and labels to your MIDI channels. You can use the colors grey, pink, cyan, violet, red, orange, green, blue, yellow.
for Example
var blazingOptions = {
inputCustomization: {
"all": { color: "grey", label: "Sum" },
"input-15-1": { color: "orange", label: "JD-Xi D1" },
"input-15-2": { color: "orange", label: "JD-Xi D2" },
"input-15-3": { color: "yellow", label: "JD-Xi A" },
"input-15-5": { color: "green", label: "System 1" },
"input-15-7": { color: "red", label: "Virus" },
"input-15-8": { color: "cyan", label: "Microkorg" },
"input-15-14": { color: "blue", label: "MFB Synth II" },
"input-15-9": { color: "blue", label: "KORG Gadget" },
"input-16-1": { color: "pink", label: "Bass Station" },
"input-16-2": { color: "violet", label: "Mininova" }
}
};As electronic music is heavily based on loops you can define length and resolution of Hot keys. This may allows all musicians to see which notes the other musicians are playing.
Define the size in [clock ticks] of a single hotSpot.
Meaningful values are
12 = 1/8 bar
24 = 1/4 bar
48 = 1/2 bar
96 = 1 bar
ATTENTION: unreasonable values may cause chaos or performance issues
Define the loop length in [bars] of a the full hotSpot loop.
Meaningful values are 1, 4, 8, 16
ATTENTION: unreasonable values may cause chaos or performance issues
If set to true an additional hot spot row with the sum of all channels will be displayed at the very top. In theory all musicians should see which base key the current music performance has.
Limit the amount of separate channels. the most active channels are on top. inactive channels disappears automatically after some time. A possible sum channel (@see hotSpot.showMerged) is excluded from this configuration value.
Here you can configure how long [seconds] played notes should be included into the hotness calculation. Keys that has been played 3 minutes before should't be treated as hot, right? This also affects the check if any input should be treated as inactive which results in hiding the channel hot spot row.
As MIDI channel 10 is the default channel for drums it might be useful to ignore incoming note events on MIDI channel 10.
Set this to false if you send keys over channel 10.
After recieving a clock start event a big timer MM:SS shows the time since last clock start. This might be useful if you want to limit live recordings to a certain limit.
When the time reaches 70% of totalTimeWarning [seconds] it gets more dominance in the GUI. When reaching 100% it turns red.
Sometimes MIDI hardware needs a stop + start event to be in sync again. To avoid a total time reset you can configure a treshold [miliseconds]. Recieving a stop followed by a start within this timerange will skip the total time reset.
As Blazing Baton is an info screen without keyboard/mouse interaction you may want to hide the mouse cursor on idle.
To disable the hiding set this to 0. Otherwise you can set any number in [seconds]
As Blazing Baton is an info screen without keyboard/mouse interaction your pc maybe activates the screen saver. Set this to true if you want to deactivate the screensaver during incoming clock events. Otherwise set it to false.
At the end of bar 16, just before starting with bar 1 again, a huge countdown is displayed in the GUI. This should sensitize all musicians to reflect this change in their playing. Here you can configure the very last part of the huge countdown 3... 2... 1... {bar16changeAnnounce}. Default value: and
